4.2.7 Communication via communication objects
The parameterisation program uses so−called communication objects to access the
931E/K servo positioning controller via a standardised software interface inside the
controller. During communication, the following error states will be internally monitored:
ƒ Write accesses to read−only communication objects
ƒ Read accesses to write−only communication objects
ƒ Value range exceeded/fallen below
ƒ Faulty data transfer
The first two errors are fatal errors that usually do not occur in practical operation. In the
last case, the parameterisation program repeatedly tries to carry out reading/writing
without bit errors.
When the value range of a communication object is exceeded/fallen below, a warning will
be displayed. If an internal value is available for the object, the value will be saved as
desired value, but the original value will be used internally, otherwise the value will be
deleted.
